Maer Roshan's new mag Radar isn't even on the stands yet, and it's already stirring up controversy. Radar reporter John Connolly was assigned an investigative piece on Doug Morris, the head of Universal Music Group. Ex-Sony Music chief Tommy Mottola has been trying to negotiate some sort of deal with UMG and wants the piece "to go away." The story isn't finished yet, but Morris is reportedly nervous because Radar is backed by ex-HBO exec Michael Fuchs, who once fired Morris when they were working at Warner Music Group. Morris returned the favor by getting Fuchs fired shortly thereafter. Next up: UMG artist 50 Cent writes rap song called "Fuchs you, bee-yatch!"Eminem's record company [FOX News]
